The B+W 39mm Circular Polarizer SC Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

B+W filters are constructed from high quality Schott glass for increased optical clarity and color fidelity. They feature a brass filter ring for durability as well as jamming prevention. This filter is vacuum coated with 1 layer of anti-reflection coating per side to help prevent internal ghosting and reflections as well as improve light transmission.

Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.

Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.

Clears up haze in distant landscapes and provides more saturated, vivid colors.

Strongest effect when used at a 90° from the sun.

Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.

Features a single anti-reflection coating per side to help prevent ghosting and reflections as well as increase light transmission from approximately 92% (uncoated glass) to over 98%.

Constructed from high quality Schott glass for optical clarity.

Brass filter ring helps to prevent jamming and provides additional strength.

Q: 1. Can you change focal length with the unit?

A: NO YOU CAN NOT!

Q: 2. Is this compatible with the Nikon Z30 yet?

A: As of right now the Nikon Z30 is not listed under their compatible cameras. However, as long as the camera body and a lens is under the weight limit, you can properly balance it and still use the Ronin-SC. But you will not have camera control on the Ronin hand grip.

Q: 3. How can the quick release plate be mounted on a tripod when moving a camera quickly between the two?

A: You can put an Arca Clamp on top of the tripod as this uses an Arca style plate. https://bhpho.to/30RPVLg

Q: 4. Is the Ronin-SC compatible with a Sony A7 iv? The DJI website says it is compatible with the A7R4, but does not mention the regular A7 iv.

A: The DJI Ronin-SC Gimbal Stabilizer has a maximum payload capacity of 4.85 pounds, so it can balance a Sony a7 IV with a light lens. However, the gimbal's camera controls are not compatible with this camera.

Q: 5. Will a Nikon d7500 and a 50mm f1.8 be able to fit on this gimbal? Or will the back of the camera bump into the gimbal?

A: The gimbal is compatible with the Nikon D7500 for stabilization use. The camera size should not be a problem for the gimbal and it's mobility.

Q: 6. Is the mounting bracket long enough for BMPCC 4k?

A: According to DJI the Ronin-SC is for Mirrorless Photography questions. It will not work with a Pocket Cinema Camera 4K. You will need to look at the larger Ronin-S and an offset plate for the Pocket Cinema Camera 4K. Ronin-S - https://bhpho.to/2FJgGoG Offset for Pocket Cinema Camera 4K - https://bhpho.to/31mQrjL

Q: 7. Will this work with the original Blackmagic Pocket Cinema Camera 1080HD?

A: Yes 100%. The following unit has a payload support of 5.5 lbs. be mindful that the original design for this unit is for mirrorless units.

Q: 8. Has anyone else had any issues connecting your ronin sc on the dji Ronin app? The app keeps crashing whenever I select my device and I'm not sure what to do !

A: It would be best to see and work with phone models that are on the compatibility list. See this link and choose your phone type Android or iPhone. https://bit.ly/38rZbx2

Q: 9. I have a 70D canon with an 18 -135mm lens that weighs 1.05 kg in total. Will it support this weight?

A: The DJI Ronin-SC Gimbal Stabilizer can effectively balance up to 4.4 pounds so it will work with the 70D and 18-135mm lens, but keep in mind that any change in the focal point will require re-balancing.

Q: 10. Sony a7iii how much weight

A: The Sony a7 III Mirrorless Camera weights 1.43 lb / 650g. The DJI Ronin-SC Gimbal Stabilizer supports up to 4.4 lb.
